[QUOTE="bigedp51, post: 1421173, member: 28965"] A picture is worth a thousand words. As you can see on the OP type runout gauge the closer to the bullet tip the more runout you will have. [IMG]https://i.imgur.com/p4gKFHe.jpg[/IMG] I have both gauges pictured below and the Hornady gauge will read half of what the RCBS gauge does. Food for thought, the Hornady gauge holds a case like a chambered full length resized cartridge would be held. Meaning the rear of the case is held by the recessed bolt face and by the bullet in the throat. And the case body do not touch the chamber walls and have no guiding effect on the bullet. [IMG]https://i.imgur.com/ed6Mwd8.jpg[/IMG] Bottom line, is the case body egg shaped or is the neck off center when you spin the case on its body. So do you full length resize or neck size your cases. And a full length resized case is more forgiving with runout and the bullet alignment with the axis of the bore. [/QUOTE]
